Hello.
This is a blocked first chakra.
You can read about opening it here:
https://joyofsatan.org/Open_Blocked_Chakras.html.
Thurs Sowilo Naud works well with the base chakra.
You need to open the upward flow of energies, which means you need to do meditations on all chakras starting from the bottom, and breathing as well.
Circulate your energies, this is important

There is a good spell from Akkadian culture for opening the chakras: Tu-Tu Gibil-Anu Zi-Ukkina.
Here I will explain a little, here are listed epithets related to purification, the ancients used similar methods with the invocation of certain forces through mantras, they have many examples in tablets, now Sumerologists call it exorcism.
The pronunciation is almost identical, as here
https://satanisgod.org/Runic_Pronunciation.html.
Only the Z is Ts, as in Kats.
That is Th-uuuuu-Th-uuuuu Ggg-iii-Bbb-iii-lll Aaa-nnn-uuuu Tss-iii-Uuu-kkkk-iii-nnnnn-aaa
You don't need to imagine here that it only affects the root chakra, it opens all chakras. Start with 13 repetitions. Yes, you also need affirmations here.
As for the sciatic nerve problem, most likely it is being pinched by the pear-shaped muscle, the exercise will help you:
I don't know what medication you are on, but an ibuprofen ointment will help with the pain, especially in severe situations, and this tends to get worse if you don't do the exercises above, then take nimesulide. You do not have allergies and contraindications to drugs, please read the instructions.
You can't do asanas like padmasana until rehabilitation. Sit in the correct position with a straight back.
And I can't sit for very long in meditation because of it.
